Key Features and Real Benefits

Built-In Hex Nut = Easy Removal

Ever tried removing a stuck oil filter? It’s messy and frustrating. This filter has a 17mm hex nut on top, so you can remove it with a simple wrench. Benefit: Faster oil changes. Less hassle. No slipping tools.

Strong Canister for High Pressure

This filter is designed to handle higher oil pressure found in V-twin engines. Benefit: No leaks. No deformation. Just steady performance.

High-Flow Filtration Media

K&N uses a performance-grade filter media that balances flow and filtration. Benefit: Clean oil without restricting flow. Your engine stays protected and responsive.

Pre-Lubed Seal for Proper Fit

The sealing ring comes ready to install and helps prevent leaks. Benefit: Secure fit on first install. No oil drips after change.

Fitment Clarity (No Confusion)

The K&N KN-171B and KN-171C oil filters are designed for many:

Harley-Davidson motorcycles
Buell motorcycles

They are commonly used on models that require a 3/4"-16 thread oil filter. Always confirm your OEM filter number or manual before purchase.

Installation Insight

Installing this filter is simple, even if you are not a mechanic.

Apply a small amount of oil to the gasket
Hand-tighten until snug
Use the hex nut only for removal or light tightening

That top nut saves time, especially when space is tight around the engine.

Who This Is For

This filter is a great fit for riders who prefer doing their own oil changes and want the job done quickly without extra effort. It works well for Harley and Buell owners who value simple maintenance and consistent performance. It also suits daily riders and long-distance tourers who need reliability on every ride. If you’ve ever struggled with a stuck filter, this makes the whole process easier and cleaner.
